摘　　要：针对内嵌式海面溢油回收装备的收油机油井油位动态控制问题,对动态斜面式收油机系统组成及工作原理进行了阐述,揭示了油井油位与斜带马达及吸油泵马达转速之间的内在规律。在提出油井油位动态检测方法的基础上,给出了吸油泵马达转速随油井油位动态变化、泵速分段自动调节原理与实现方法,建立了吸油泵马达转速控制系统数学模型,运用Matlab/Simulink仿真软件对其转速控制系统进行了仿真分析;构建了实验测试系统,并且进行了测试验证。研究结果表明:吸油泵马达转速控制系统响应速度快,0. 16 s后输出稳定;马达输出转速随油井油位分段自动调节,当油井油位处于不同区间时,吸油泵马达可自动调整其转速至650r/min、485 r/min及320 r/min;实验测试结果验证了该油位动态控制方案的正确性,满足系统设计要求。Aiming at the problem of oil level in oil well of receiving machine for embedded type oil spill recovery equipment dynamic controlling,the constitution and working principle of the dynamic inclined plane type receiving machine were expounded,the inherent law between the oil level and the speed of the ramp motor and the oil suction pump motor was revealed. The principle and realization method of the oil suction pump motor rotating speed which changes dynamically and regulates segment automatically with oil level were given,on basis of proposing method of dynamic detecting oil level. The mathematical model of the oil suction pump motor speed control system was established and simulated as well as analyzed using the Matlab/Simulink software,and the experimental test system was also built to verify the scheme.The results indicate that the oil suction pump motor speed control system responds quickly,has a stable output after 0. 16 second. The motor rotating speed can adjust segment automatically with oil level,when the oil level is in different intervals,the suction pump motor can adjust its speed automatically to 650 r/min,485 r/min and 320 r/min. Experimental results verify the correctness of the oil level dynamic control scheme,and it meet the design requirement of the system.
